This book was released on 2012-11-28 with total page 1736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides a comprehensive review of the nomenclature and distribution of the Geadephaga of America, north of Mexico. Overall 2439 valid species-group taxa in 208 genera are catalogued along with their synonyms. Besides the usual information pertaining to author(s), date and page of publication, the type locality, location of name-bearing type, first reference establishing each synonym, and etymology for many patronymic names are provided for species-group names. Genus-group names are listed with the author(s), year of publication, page citation, type species with manner of fixation and etymology for most. The geographical distributions of all species-group taxa are briefly summarized and their state and province records are indicated. About 2500 references are listed with publication dates for many in order to assess priority of names.Several new nomenclatural acts are introduced including one new genus-group taxon, one new replacement name, three changes in precedence, five new genus-group synonymies, 65 new species-group synonymies, one new species-group status, and 12 new combinations.The work includes also a discussion of the notable private North American carabid collections, a synopsis of all extant world geadephagan tribes and subfamilies, a brief faunistic assessment of the fauna, a list of North American fossil Geadephaga, a list of North American Geadephaga larvae described or illustrated, a list of species described from specimens mislabeled as from North America, and a list of unavailable names listed from North America.

Book excerpt: Indexes the world's zoological and animal science literature, covering all research from biochemistry to veterinary medicine. The database provides a collection of references from over 4,500 international serial publications, plus books, meetings, reviews and other no- serial literature from over 100 countries. It is the oldest continuing database of animal biology, indexing literature published from 1864 to the present. Zoological Record has long been recognized as the "unofficial register" for taxonomy and systematics, but other topics in animal biology are also covered.

Download or read book Mechanisms of Sound Production in the Ariid Catfishes Galeichthys and Bagre written by William N. Tavolga and published by . This book was released on 1962 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The skeletal basis of the sound producing mechanism in the ariid catfishes Galeichthys felis and Bagre marinus consists of a thin shelf of bone which is firmly attached to the anterior dorsal wall of the swim bladder. This so-called 'elastic spring,' or 'Springfederapparat,' is formed from the parapophysis of the fourth vertebra. The anterior ramus of this parapophysis, herein named the 'Müllerian ramus' (after Johannes Müller who, in 1842, first described the structure), is the main vibrating element in sound production. The skulls and anterior vertebral complexes of Galeichthys and Bagre are figured and described, with comparisons with a non-sonic silurid form, Wallago. The 'protractor muscle' (so named by Bridge and Haddon in 1893) which activates the Müllerian ramus is a highly vascularized conical muscle, the origin of which is on the under side of the epiotic lamina and insertion on the Müllerian ramus. It is innervated by the dorsal branch of the occipital nerve. The relationship of this nerve to the cranial nerves of higher vertebrates is controversial, but it is probably homologous with the hypoglossal (XII). Stimulation of the protractor muscle or its nerve supply with repetitive spike-form potentials results in an audible sound output from the Springfederapparat. This response can be recorded and analyzed, and its fundamental pitch is equivalent to the pulse frequency of the stimulus. The protractor muscle is remarkable in that it can withstand stimulations of 300 or more pulses per second without going into immediate tetany. In Bagre, the frequency response of the sonic system is about an octave higher than that in Galeichthys. Spontaneous sounds from these species consist of low-pitched grunts (fundamental pitch of about 150 cycles per second) and, in Bagre, higher, sob-like sounds (400 cycles per second or over). The harmonic components of both artificially induced and spontaneous sounds can be influenced by the amount of sound reflectance in the external environment. Even under partially anechoic conditions, the sound output is virtually a pure tone. Damage to the swim bladder reduces the amplitude of the sound but not its timbre (i.e., harmonic content). It was concluded that the swim bladder does not serve as a resonating chamber for these sounds, nor is it a true amplifier. Rather, it transfers the energy from the small area of the vibrating Müllerian ramus to the larger area of its entire outer surface, thus making the propagation of the sound from its source to the water more efficient. In acoustical and electronic terms, the swim bladder is an impedance matching device"--P. 27.
